Study Jams: Weathering and ErosionOver time, the natural environment gradually changes due to weathering and erosion. Although the changes happen slowly, the results can be spectacular. Just look at the Grand Canyon! Compare weathering and erosion to superheroes who break things down and carry them away. Weathering breaks rocks down into sediment and erosion carries it away. Water, wind, acid rain, rust, and extreme temperatures break things down. Water, wind, gravity, and glaciers can carry sediment away and deposit it somewhere else.
